The RMT said Southern had refused 'unconditional' talks point blank.
General secretary Mick Cash accused Southern of being 'hell bent on confrontation'.
Govia Thameslink Railway has offered an 'implementation' payment of £2,000 to each conductor who agrees to become an on board supervisor, but also warned that the deadline for the offer was midday Thursday, after which it could be withdrawn.
The company has also said that conductors who did not agree could be given notice alongside the offer of a new on board supervisor contract to start in January.
